.CONDENSEIi Application ledNovember 10, 1926.-' SeriallNo. 147,411.` Y

This invention relates to steam condensers and more particularly to surface condensers inwhich the non-condensible fluids, suchv as airfare -separated troni thecondensible fluids and are"`cooled in an air cooling Zone to .as low` a temperature and specific volume as possiblefpriorvto their delivery to the dry vacuum pumpj which withdraws the air troni the co'ii'c-lei'1sei".l l l An object of the present.inventionis to provide 'in Condenser as. specified; means for'preventing Athe flooding of the dry .vacuuuipunip and securing the coolingf and evacuation off theair in instances wherethe con- 'densate'rises to such level as to close the usual suction inlet to the air coolingaone of" the condenser. y llVith these objects in view, the invention consists in'lvario'us' features of construction and combination of parts, which Will be first described in connection with the accompanying drawings5, showing a condenserof the preferred forni embodying the invention, and the' eaturesfforining the'invention will be` specifically pointed out inthe claims.

InFiguresl. tooffthe` drawings the emergency entrances :or ,inletsr are. torni-ed by .pipes Swhich are attached .to and. suit-v ablyy supported by the yballles 3 .and f 4 above the lower. edges not the Abaliles and between the normal air inlet .to the airrcoolingry Zone and the air suctionor outlet Thepipes 8 extend .from a point ,wellwithinthe tubev liest or troni-among the. tubes outside ot the air` cooling` Zonev and these pipes: may extend throughfthe bellies, orto the balllesf; linthe latter `instances the ballles have suitable openings coinnuinicating` with the pipes. to `permit the airrto pass lthrough theapipesl into the cooling zone 6. To cause maximum cool- Iingof the air enteringthe cooling. Zone' 6 through the emergency inlets S, thexballles 10. are vprovided which incline towards the .norinal air inlet andiaway from the airfsuction pipew so as toicausevthe air to pass over as many tubes as possible duringfits passage ,throughthe air coolingzone.. s

Lln Figure 4.- of thed'rawings :a .modified forni. of the condenser 1s shownlin whlehfthe air cooling zone 20 is positioned at one side ,of the condenser-in lieu ofthe 'center of the condenser as showninFigureswlito/B 1nelusive.v In the-.modified forni of the'invention where eoolingzone 21 `is'confinedqby vthe baille-22 which :extends i from the" condenser shell 23 .downwardly and inwardly condenser, and entrance of air into the air cooling zone 2l is across or beneath the inner lower edge oi the baille as indicated by the arrow Il. The air suction 24.- through which the air passesl from the air cooling zone to the dry vacuum pump is directly beneath the uppermost portion oi the baille Q2 and at the top ot the air cooling zone 2i. To permit passage oi ai: i'roni within the condenser into the cooling zone Qi when the condensate rises to such a level as to close the normal air inlet to the Zone, (such condition being illustrated in the drawing) tubes` or pipes 25 are provided which extend through the baille f trom within the tube nest outside oi the air cooling zone to a inidposition within the air cooling' zone. Bailles 26 are provided ior directing the air which enters the cooling zone through the pipes or tubes downwardly to cause it to pass over as large a number oi tubes as possible prior to its passage through the air suction 2i.

A drain L7 is shown for draining condensate from oil' the top oi` the baille '22 to the hot well 2S ot the condenser structure.

From the foregoing description taken in connection with the accompanying drawings` it will be apparent that a condenser structure has been provided which will prevent flooding of the dry vacuum pump in instances where the condensate rises to such level as to close the usual or normal inlet to the air cooling zone of the condenser and it will be understood that the invention is not to be limited to the specific construction or arrangement ot parts shown but that these may be modiiicd widely within the invention dciined by the claims.

lVhat is claimed is:
